Very similar to vrykul, these creatures are covered in green scales, barnacles, and seaweed. When they die on land, they evaporate, leaving behind only their weapons and any seaweed or objects that were on their bodies. When killed in the water, they leave behind intact corpses.they also only appear on the shore.

The kvaldir cannot exist outside the mist with the exception of the raiders in Kaskala, however, this could simply be that Blizzard opted not to cover the area in mist. It is possible that the kaskalan Elder Muahit's quest to secure the aid of the elements against the kvaldir raiders is impacting the area. He mentions that the weather is assisting the Tuskarr, possibly by driving away the mist.
